Mount Sinai (MPhil) Mount Sinai (M Phil) Joy S. Gaylinn Reidenberg is an American comparative anatomist specializing in the vocal and breathing apparatus of mammals, particularly cetaceans (whales, including dolphins and porpoises).

She is best known as the Comparative Anatomist in the TV science documentary series Inside Nature's Giants.

In 2009, a British production company approached her about coming to Ireland on short notice to help dissect a 19.8 m (65 ft) fin whale that had washed up on the south coast.

She conducted the dissection, and the company was so happy with her performance that they asked her to become a regular contributor to Inside Nature's Giants, dissecting a variety of animals (18 episodes in total), including: fin whale, sperm whale, lion, tiger, elephant, giraffe, hippo, crocodile, python, great white shark, giant squid, camel, kangaroo, cassowary, baboon, leatherback sea turtle, polar bear, race horse, giant jungle insects.

Reidenberg works in New York City and is a professor at the Icahn School of Medicine at Mount Sinai's Center for Anatomy and Functional Morphology,[5] where she teaches in the Structures Course (Gross Anatomy, Histology, Embryology, and Imaging).
